The Iguazu falls are the largest system of waterfalls in the world. Situated on the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná, they separate the river into the upper and lower Iguazu.

We were staying in the city of Foz do Iguaçu in Brasil, having crossed the border from Paraguay in the morning. Foz do Iguaçu is the Brasilian gateway to the falls and so easily accessible by public transport. Stepping off the bus we were blown away at the vista in front of us, a panoramic view of waterfalls spanning from left to right as far as the eye could see. It’s not surprising that it was recently voted one of the new seven wonders of nature.

Throughout the trip we have heard differing views on whether it is better to visit the falls from the Brasilian or Argentinian side. Having enjoyed visiting them in Brasil so much we decided to see them from Argentina the following day. While Argentina lacked the panoramic view of the Brasilian side, it allowed you to get much closer to the action, with walkways of different heights right up to, and in some cases on top of, the falls. A particular highlight was being perched above the Garganta del Diablo (Devil’s throat), the largest of the falls at 82 x 150 x 700 metres, which funnels around half of the river’s flow. With around 1,500 cubic metres of water flowing over the falls every second, the seemingly endless stream of water creates a momentous roaring and permanent mist that looms over the abyss, broken only by the occasional darting of some rather daring swallows.

From Foz do Iguaçu we also visited Parque das Aves, the largest bird park in Latin America, with more than 1,320 birds from about 143 different species. Housed in 16.5 hectares of rainforest next to the falls, the birds are predominantly rescued and rehabilitated before being released back into the wild. One of our favourite things about the park was the number of walk-in cages, where you could see many of the birds up close, including a huge cage housing around 30 varieties of parrot and parquet . The sea of colour flying over your head was incredible.

Situated 30km north of Buenos Aires, Tigre is a town that lies on the Paraná Delta, consisting of several islands and covering 14,000 square kilometres. It takes its name from the tigers that were hunted there in its early years. Initially it was settled by Europeans who had come to farm the land. Later the port was developed so that fruit and wood could be transported along the Paraná river. One of the islands features a house built for the former Argentinian president Domingo Faustino Sarmiento in 1855. Following his death it was declared an historic monument. It now serves as a museum and is enclosed in glass walls for protection. Although parts of the town are interesting it is sadly something of a tourist trap now, with a theme park, speedboats and jet skis ruining what could be a tranquil place.
